Signs of Wound Infection

Wound infection symptoms can start up to a month after you receive the initial wound.5 Common signs of infection include:

  • Redness3 or dark streaks spreading around the cut6

  • Hot to touch and tender skin3

  • Swelling or pain3

  • Blood or pus coming from the wound3

  • Fever3

Speak to a doctor if you notice any these signs.

How to tell if a wound is infected or healing

It can be hard to tell the difference between a healthy vs infected wound, especially if you're not sure what the healing process looks like.

One of the key distinctions is the type of fluid produced by the wound, known as wound drainage. If you notice a clear or pink fluid seeping out, this is a sign that the wound is healing. In contrast, an infected wound usually produces yellowish pus and may smell bad.7

How to treat an infected wound

Many minor infected wounds can be treated at home with the help of over-the-counter products such as the range of wound care products from NEOSPORIN®. For more severe infections or deeper wounds, you should seek help from a doctor or wound care specialist, who may recommend further treatment or a tetanus shot.8

Below, we'll cover basic cleaning and care for wound infections, as well as what not to do.

How to clean a minor infected wound

All wounds should be cleaned regularly, especially if you think they could have a minor infection.3 Just follow this simple step-by-step guide to help keep your infected wounds clean:8

  • Sterilize your equipment. You can use rubbing alcohol on cotton wool to sterilize the tip of your tweezers9

  • Wash your hands with soap and warm water, then dry them properly8

  • Rinse the wound under running tap water8

  • Cleanse the skin around the wound with soapy water, making sure not to get any in the wound,8 or clean with an antiseptic wash

  • Check for dirt or debris in the wound and use your sterilized tweezers to remove any8

  • Apply a thin layer of antibiotic ointment, such as NEOSPORIN®, to prevent the spread of infection8

  • Wrap your wound in a bandage to protect it and retain moisture8

  • Change the dressing at least once a day, or sooner if it's wet or dirty, and keep an eye out for signs of infection8

Basic first aid for wound infections

There are several basic first aid options for treating and healing infected wounds at home, from over-the-counter antibiotic options to natural cleansing solutions:

  • NEOSPORIN® Ointments & Creams – a triple antibiotic ointment which uses an effective germ-killing formula to provide 24-hour infection protection. There are also NEOSPORIN® products to help reduce itching and pain and minimize scarring, in addition to their infection protection capabilities!

  • Bacitracin – an over-the-counter antibiotic ointment that can help treat minor skin injuries and prevent infection10

  • Amerigel® Hydrogel Wound Dressing – a hydrating treatment that provides a moist wound healing environment and helps reduce scarring but does not provide infection protection or prevention

  • Salt water, or saline solution – a cleansing solution for wounds, because it is non-toxic and does not damage healing tissue.11 However, it does not provide any infection protection or prevention

Just remember that these treatments are only suitable for minor infections. Severe wounds should be looked at and treated by a specialist doctor or nurse.

What not to do

  • Don't pick your wound or scab as it can rip the new skin underneath and take longer to heal12

  • Don't use hydrogen peroxide or iodine to clean your wound as this can cause further irritation

Wound Infection Healing Stages

There are four main phases of wound healing:13

  • Hemostasis – the cut occurs on the skin or tissue13

  • Inflammatory – the wound starts to close13

  • Proliferative – new tissue begins to form over the course of a few weeks13

  • Remodeling or maturation – the longest part of the process, which can take between 12 and 24 months. Usually leaves some type of scarring13

How to Prevent Wound Infections

Understanding how to prevent an infection is just as important as knowing how to treat an infected wound. Here we'll outline the potential risk factors, as well as measures you can take during the healing process to reduce the likelihood of infection.

Risk factors

Anyone can develop an infected wound, but there are certain factors that can increase your risk of infection3. These include:14

  • Weak immune system

  • Diabetes

  • Obesity

  • History of smoking

  • Malnutrition

  • Decreased mobility or immobility

  • Poor hygiene

  • Poor circulation

Using NEOSPORIN® to prevent infections

You can use the NEOSPORIN® Wound Care products during the healing process to help treat your wounds and prevent infections. Antibiotic ointments, such as NEOSPORIN® Original Ointment, can be applied to the wound for 24-hour infection protection.

Similarly, SIMPLY NEOSPORIN™ uses only three ingredients – bacitracin zinc, polymyxin B sulfate and petrolatum – to help prevent infection in minor cuts, scrapes, wounds and burns.

Other ointments such as NEOSPORIN® + Pain, Itch, Scar go above and beyond, addressing five areas of wound healing: infection protection, pain relief, itch relief, scarring and skin nourishment.

NEOSPORIN® is the #1 doctor recommended brand of topical antibiotic in the U.S.


How do I know if a wound is infected?

The most common signs of wound infection are warmth and redness around the wound, as well as tenderness, swelling or pain. You may also notice pus seeping from the wound, rather than a healthy clear or pink fluid.

What is the best antibiotic for infected wounds?

The best antibiotic treatment depends on the type of wound, where it is on the body and how infected it is. Minor wound infections can be treated with over-the-counter topical antibiotics, such as NEOSPORIN® Original Ointment. Severe wounds will need to be seen by a doctor.

What is wound sepsis?

Wound sepsis is a potentially life-threatening condition that occurs when infection-fighting processes turn on your body.15 It can lead to septic shock if not treated, so speak to a doctor if an infected wound is not healing – as this could be an early sign of sepsis.12
